CVE-ID CVE-2014-1318 : Ian Beer of Google Project Zero working with HP's Zero Day Initiative IOKit Kernel Available for: OS X Mavericks v10.9.2 Impact: A local user can read kernel pointers, which can be used to bypass kernel address space layout randomization Description: A set of kernel pointers stored in an IOKit object could be retrieved from userland. This issue was addressed through removing the pointers from the object. CVE-ID CVE-2014-1320 : Ian Beer of Google Project Zero working with HP's Zero Day Initiative Kernel Available for: OS X Mavericks v10.9.2 Impact: A local user can read a kernel pointer, which can be used to bypass kernel address space layout randomization Description: A kernel pointer stored in a XNU object could be retrieved from userland.

To prevent attacks based on this scenario, Secure Transport was changed so that, by default, a renegotiation must present the same server certificate as was presented in the original connection. This issue does not affect Mac OS X 10.7 systems and earlier. CVE-ID CVE-2014-1295 : Antoine Delignat-Lavaud, Karthikeyan Bhargavan and Alfredo Pironti of Prosecco at Inria Paris WindowServer Available for: OS X Mountain Lion v10.8.5, OS X Mavericks v10.9.2 Impact: Maliciously crafted applications can execute arbitrary code outside the sandbox Description: WindowServer sessions could be created by sandboxed applications.
